To all whom it may," concern:

Be it known that I, EVI W. CHmsTm,-Ya citizen'- of the United States, residing Sewaren, in the county of Middlesexand State of blew Jersey, have invented an I I provement in Surface Condensers, of which thefollowing is a specification.

My present invention relates to condensers, and particularly to surface condensers, and the object thereof is primarily the provision of a surfa'ce condenser adapted forms with steam turbines having two ex: haust connections, although, as will be understood, the invention is not limited to this particular use.

- The. condenser made in accordance with my present invention isdesigned to provide sufficient condensing surface for the use intended thereof, and also to eliminate extra piping and other complications incident to the employment v of two separate and. independent-condensers for this work. 5

In carrying out'my invention, I preferablyemploy a plurality of casings, each having an eshauststeam inlet, and a condensed steam outlet, a bank of tubes infeach casing,

. a, circulating liquidi'nlet ando'utlet chamber condenser preferably comprises a shell or" between each adjacent casing, and an equalizing chamber extending between the ad a'- cent casings so that the vacuum in each will.

be the'same, as will be hereinafter more particularly described.

In the drawing, Figure '1 is a central longitudinal 'crosssection of a, condenser made ina'ccordance with mypresent inven-* tion, and Fig. 2 is an end elevation thereof. Referring to the drawing, my mproved casing, indicated at 10, providedwith an exhaust steam inlet 11 and a condensed steam 'outlet 12, and also a shell or casing 13,

similarly provided with an exhaust steam inletls or a condensed steam outlet 15. In the casing 10, there is a plurality of tubes arranged in banks, one of which is indicated at 16 and the'other at 17. At their ends, these tubes, as is customary, are suitably connected in tube platcs,. 18 and 19, connected respectively to the opposite ends of the casing 10. Similarly in the casing 13 there is a pluralityol? tubes arranged inbanks, indicated at .ZOaud 21. These tubes,'

. as is also customary, are, at their ends, fixed "in tube plates 22 and 23, suitably secured to the opposite ends ot the casing 13.

condenser, the circulating water 'is ad-' ing chamber 29, which, through suitable apertures in the. tube plates 18 and 22 makes communication between the interior of the casings 10 and 13, so as to equalize the vacuum in these casings;

- At its outer end, the casing 10 is provided with a Water box 30, fitted with a cover 31, 1

in which there may be provided suitable arm holes 32. Similarly, at its outerend, the

cas1ngl3 is provided with a water box 33',

fitted with a cover 34. l 4

Inzthe use of the hereinbefore 'described mitted atthe. inlet connection 25, to the in let chamber in the water box 24, from which it divides, a portion passing through, the bank of tubes 17, in the casing'lO, to the.

water box 30, thence through the bank of' tubes 16 to the outlet chamber of the water box'2l. The other part of the circulating Water passes through the bank of tubes 21, in the casing 13, to the water'box 33, thence through the bank of tubes 20 to the outlet chamber of thewater box 24, as is indicated by the arrows shown in Fig. 1;

The exhaust steam from the turbines, or other source, is connected by 'suitablepiping to the inlets 11 and 14, and thence comes in 9 contact with the outer surface of the tubes in the several banks and is condensed thereon, the Water of condensation being suitably conveyed from the condenser casings through 1 the outlet connections 12 and 13.

clain-i as my invention: 1. A surface condenser comprising a plu rality of condenser shells in aline'ment and each having an exhaust steam inlet and a condensed steam outlet, a tube plate atthe ends of each condenser shell, banks of tubes in each condenser shell, a Water box casing placed between and secured to the edge-cent tube plates of adjoining condenser shel s and having inlet and outlet connections, means 119 ends of the condenser shells.

- for equalizing the pressure in the condenser shells, and Water box casings at the distant 2- A surface condenser comprising a plurality of condenser shells placed in aline-' *ment and each having an exhaust steam 1nlet and a condensed steam outlet; a tube plate at the ends of each condenser shell, banks of tubes secured in and extending between the tube plates of each condenser shell, a Water box casing placed between and secured to the adjacent tube plates of adjoining condenser shells and having inlet and outlet connections, a partition plate in the said Water box casing dividing the same into two compartments, means for equalizing the pressure in the condenser shells, and Water box casings at the distant ends of the condenser shells.

3. A surface condenser comprising a pair of similar condenser shells placed in alineinert and having an exhaust steam inlet and a cc-itlensed steam outlet, a tube plate at the ends of each condenser shell, tubes secured in and extending between the tube plates oI each condenser shell, a Water boX casing placed between and secured to the adjacent tube plates of achoining condenser shells and having inlet and outlet connections for the circulating Water, a partition plate in the said Water box casing extending between the adjacent tube plates, in which there are 'ports through which and the chamber made in the Water box casing by the said partition plate, communication is provided between the said condenser shells, and Water box casings at the distant ends of the said each of the said condenser shells, a Water box casing placed between and secured to the adjacent tube plates of adjoining condenser shells and having inlet and outlet 'connections for the circulatingwater, a partition dividing the said water box easing into compartments 'for the circulating Water, a

second partitionin one 01 the said compart-.

ments of the Water box casing extending between the adjacent tube plates, in which ports are provided, through which ports and the chamber made inthe Water-box" casing by the second partition a communication is provided between the interior of the condenser shells, and Water box-casings at the distant ends of the said condenser shells.
